Abstract
A system for media handling and uniformity calibration for an image scanner includes an optical window, an assist roller, an adjustment mechanism, and a calibration strip. The assist roller receives and guides media through a gap between the assist roller and the optical window. The adjustment mechanism is integrated with the assist roller for controlling the distance between the assist roller and the optical window for smooth passage of media. The controlled reflectivity calibration strip connected to the adjustment mechanism facilitates sensor calibration, such as flat field correction. The adjustment mechanism moves to position the calibration strip in alignment with the optical window whenever sensor calibration is desired.
